New Version 2.7.1 Released

This is primarily a bug fix release for version 2.7.0
It is highly recommended to update 2.7.0 installations with 2.7.1 

To use this release you need to have version 1-12 of LONCAPA-prerequisites  
installed.
 
If you are upgrading directly from 2.6.3 or earlier, the following applies to you: 

One of the changes for 2.7 affects scantronformat.tab. After you have installed
2.7.1 on the primary library server in your domain, log-in,
select the Domain Coordinator role, and go to "Domain Configuration".
Check the box for "Scantron format file", click "Go", and if you currently
use a customized scantronformat.tab file it will be copied (behind the scenes)
from its current location to a new location where it will be 
available for selection whenever scantron grading is used in a course 
in your domain.

Changes from 2.7.0

Bug fixes for 2.7.0-specific bugs

- Dynamically generated plots are rendered again where a value has been included 
 for the minorfreq in the ytics tag. 
- Resources in a folder are available again for selection when printing the 
 contents of a folder in Construction Space.
- Generation of printouts works again for vector problems for which multiple answers 
 are required, but some have not been submitted.
- Domain Coordinators can again select co-author roles assigned to them in other domains.
- Spaces are no longer removed from submissions to stringresponse problems prior to grading.
- Stringresponse problems, for which a type (cs, ci, mc or re) has not been set, are again
 graded correctly in cases where the first or second character in the submitted string is a number.
- A list of accessible portfolio files can again be reached from a user's personal web page 
 ("aboutme" page).
 
Bug fixes for other general bugs

- Complete breadcrumb trail now provided to students viewing Supplemental Documents, thereby 
 allowing access to top level items, once items deeper in the hierarchy have been viewed.
- Pasting an item from Supplemental Documents to Main Documents no longer results in artifacts
  from HTML tags in the item title. 
- More comprehensive format checking used for usernames of collaborators in problems 
 allowing submission by teams of students. 
- Parameter Helper and Slot Manager now include current time zone when setting dates/times.
- Testbank importer in Construction space now displays an error message (including type of 
 file uploaded) if the file was not plain text, RTF or HTML.   
- Problems set to type "Practice" are available for selection when printing just problems from
  a folder.
- The broadcast e-mail utility for Domain Coordinators can now convert usernames for locally authenticated users to e-mail addresses if the generic address to append is entered (e.g., msu.edu).
- Automatic offloading of sessions from an overloaded server to a server listed in spare.tab now supported where the destination server uses SSL, if https has been included as an additional entry in the dns_hosts.tab for that server (send updates to loncapa@loncapa.org).  
- Access to submissions for problems with encrypted URLs from links in the course assessment
  progress chart (CHRT) now works for TAs.
- Display of problems with encrypted URLs now works for TAs when using "View" links available 
 for some items in "course assessment statistics" (STAT).


Enhancements
- "Edit Answer" button used to open a pop-up DragMath, JME Editor, or Chemical reaction Editor
  pop-up window replaced with a pencil icon to the right of the text box used to enter the answer.
- A new parameter is provided to suppress the availability of the DragMath WYSIWYG Math Editor 
 (default is for it to be available) for Math response and Formula response items.
- Access control based on IP address extended to other resources in a course besides problems.
- Algebra tag can include a display attribute to dictate which math rendering is to be used 
 (tth, jsMath, mimetex).
- Disply of events in the calendar now consistent with current time zone 
 (included in Calendar header line).
- Instructional staff can generate printouts from the entire course for selected people.
- Launch Remote control link removed from inline navigation menu to reduce congestion  
  (all users will now need to visit User Preferences to launch the remote control).
- Authors can assign more than one target language for a particular <lang> block when creating multilingual resources.

To install this update:

1) You will need to be running Fedora Core 6, 7, 8, or 9, RHEL (AS|ES) 4 or 5,
    SUSE 10.1 10.2 or 10.3, SLES 9 or 10, CentOS 5, Scientific Linux 5
      (Fedora Core 5 should continue to work but is deprecated.)

2) Update to the latest LONCAPA-prerequisites (1-12) 
   (skip if upgrading from 2.7.0)   
w

(a) Fedora
yum update

(b) RedHat Enterprise 4 

up2date -u LONCAPA-prerequisites

Note: LONCAPA-prerequisites for Red Hat Enterprise Linux 4 includes 
a dependency on perl-libxml-enno-1.03.  If you already have perl-libxml-enno
iinstalled on your system it will be version 1.02.  If the update to
LONCAPA-prerequsites 1-12 fails to update perl-libxml-enno to 1.03,
you should update that package directly:

up2date -u perl-libxml-enno

(c) Red Hat 5/Centos 5/Scientific Linux 5 

yum update

(d) SuSE/SLES 

Use yast-> Installation Source to refresh the LON-CAPA repository
Use yast->Software Management->Search to update LONCAPA-prerequisites (to 
version  1-12). 

For SLES9, use yast->Software Management->Search to also update latex-ucs
(to version 20041017-31) after refreshing the LON-CAPA repository.   

On all distributions, it is recommended that you check that you have the 
correct versions of LONCAPA-prequisites installed before proceeding. 

rpm -q LONCAPA-prerequisites

should report:
LONCAPA-prerequisites-1-12.X

(where X is a distro identifier e.g., fc7.lc) 

If you are using Red Hat 4, also check that you have 
perl-libxml-enno version 1.03

rpm -q perl-libxml-enno

should report:
perl-libxml-enno-1.03-1.rhel4.lc 

3) Download the new LON-CAPA tarball from
wget http://install.lon-capa.org/versions/loncapa-2.7.1.tar.gz

and untar it

tar xzvf loncapa-2.7.1.tar.gz

4) stop the LON-CAPA system services

/etc/rc.d/init.d/loncontrol stop

5) stop the webserver:

Fedora/RHEL/Centos/Scientific Linux
/etc/rc.d/init.d/httpd stop

SLES 9:
/etc/init.d/apache stop

SUSE 10.1/SLES 10:
/etc/init.d/apache2 stop


6) Run the UPDATE script as root
cd loncapa-2.7.1
su
./UPDATE



7) restart the LON-CAPA system services
/etc/rc.d/init.d/loncontrol start
